To all whom it may concern/.

Be it known that I, CHARLES FREROT, mann facturer, a citizen of the Republic of France,

. residing at Rheims, (Marne) France, have 111- vented a certain new and useful Machine forthe mechanism illustrated in the accompanyis the mandrel 14, consisting'of a hollow cyl-,

Fig. 8 is a side View of the mandrel, and Fig. 9 is a section thereof on line 19 19 of Fig. 8- l Similar characters refer to similar parts throughout the several views.

One of the principal organs of the machine inder sliton its whole length following a gencrating-line. This mandrel is fastened to the end of a'shaft 15,-the other end of which is provided with teeth, soas to form a pinion16. Some of the teeth 16-t hree, forinstance--run through the whole length of the shaft. The pinion 16 is connected, by means of the gearings 17, 18, 19,20, and 21, with the shaft 22, which receives its movement, through the instrumentality of bevel-'gearings, from the impelling-shaft 24, bearing two pulleys 23 23,

one of which is fixed on the-shaft, while the other runs loose.

The mandrel 14 and the shaft can move longitudinally in their respective bearings 25 Fig. 6 is a cross-sec- :and 26, and the shaft 15 is provided with a head 27, on which are'pivotedthe connectingrods 28, which in turn are pivoted at their opposite ends on the connecting-rod 29, which latter is mounted on a pivot 30. The pivots of the head 27 are provided with rollers 31,

running between the guide-bars 32 32, which latter are fastened in the slots 33" by bolts 33,

, which allow the bars to be adj usted vertically in position parallel to the frame of the machine,so that the said head and the shaft 15 j are guided in their translating movement and are given a straight-line motion. The connecting-rod 29 is in operative relation, by

'means of the connecting-rod 35, with the coninecting-rod 34, as clearly shown in Fig. 2. The connecting-rod 34 being hinged on a pivot 36 has a slot 37 wherein slides the pin 38 of the disk 39, mounted on a shaft 40, which latter can be acted on by theshaft 22, with which it is connected by means of the bevel-pinions 43 44 and by the intermittent straight gearing 41 42. '34 is circular in its part a b c, and its mean ,r'adius is equal to'that of the distance from The slot 37 of the connecting-rod the center of disk 39 to the center of pin 38. The mechanism on which the sheets of paper,'cardboard, or pasteboard are placed consists of an oscillating table; 46, held by the two pieces 4'7 and oscillating on the shaft 48.

The oscillation is obtained by the action which'the cam 50, mounted on the shaft 51,

efiects on the roller 49, Fig. 7. The shaft ;51 is connected with the shaft 22 by means of straight gears and bevel-gears, which are mounted on the shafts 52 and 53. Two guides 54, placed on the table 46,-and a butt-plate 55, the positions of which are adjustable,-serve to receive and lead the sheets. A cylindric brush 56, with an open part (1 e, is mounted on a shaft 57, running parallel to the mandrel 14. This shaft 57 is connected, through the gearings '58, 59, and 60, with the shaft 53, as shown in Fig. 7. A curved pallet 61, placed underneath the brush 56, is fastened to the two vertical bars 62, tied together by the'horizontal stay 63. These bars 62, sliding in the guides 64, which are fixed on the standards 65,'receive their movement from the shaft 53 by a cam 66, acting on a roller 67 pin 69. The glue is contained in a receptacle 70, arranged under the curved pallet 61, and the brush 56 is disposed in such a way that it constantly rubs on a horizontal bar 71.

Underneath the mandrel 14 is a bar 72, fastened on the supports 73, which oscillate on the pivot 74 through the action of the cams 75, mounted on the shaft 53.

A mechanism destined to receive the finished tubes is arranged under the table 46. This mechanism comprises a table 76, supported by two bars 77, sliding in the guides 78. The bars 77 receive their movement from the shaft 51 by means of the cams 79 and a set of levers 8O 81, which are provided with springs 80 for the withdrawing movement, one end of each spring being secured to a fixed pin 80.

All the devices heretofore described and the different organs put in movement by the same are fastened on a table 82, which rests on the standards or legs 83.

The arrangement of the machine being thus described, I shall now proceed to explain its working: IVhen the sheet of paper, cardboard, or pasteboard is cut to the size desired, it is placed against the guides 54 of the table 46 at the moment when the latter is in the position shown by dotted linesin Fig. 7. Then the sheet is given the position required with regard to the mandrel 14 by making it butt against the butt-plate 55, which is suitably adjusted beforehand for this purpose. Now while the table 46 is lifted the mandrel 14 undergoes a movement of translation by being withdrawn from its position in front of the said table until its end f is in a plane with the face h of the support 25. This translating movement is imparted to the mandrel .by the rotation of the disk 39, whose pin 38 moves in the slot 37 of the connecting-rod 34, and thereby makes the latter oscillate until the pin arrives at the initial point 0' of the circular part ab 0 of the slot and the center 45 of this part is in line with the center of the shaft 40. It will be easily understood that the oscillation of the connecting-rod 34 results in a translating movement of the mandrel 14, since the latter is connected with the same by means of the shaft 15, the head 27, and the swing formed of the articulated connectingrods 28 29 35. As long as this translating movement lasts the mandrel 14 does not turn, because the intermittent wheels 20 and 21 are arranged in such a way that their inactive parts are in contact with each other while this movement is going on. It follows that the gearings 20 19 18 17 being at rest the pinion 16 does not turn either, while the teeth running through the whole length of the shaft 15, owing to an appropriate disposition of the same, gear with the teeth of the wheel 17, so that as long as the translation of the mandrel lasts any displacement of the wheels 17 18 19 is made impossible, whereby a good and secure working of the intermittent gearings 20 and 21 is obtained. On the other hand, the arrangement of the mechanism is such that the centers 45 and 40 are identical at the same moment when the endf on the mandrel 14 is in a plane with the face it of the support 25. At this moment the table 46 is lowered in a manner as to present the edge of the sheet to be worked on right in front of the slit of the mandrel 14. Meanwhile the pin 38 travels in the circular part a b c of the slot 37 of the connecting-rod 34 which then occupies a position opposite to thatshown in Fig. 2, yet it does not displace the connecting-rod 34 as long as its center and its radius are the same as that of the circular part a b c of the slot or groove wherein it moves; but continuing its rotation it begins to move the articulated connecting rods and levers 34, 35, 29, and 28 in an opposite direction as soon as it reaches the point a of the circular part a b c of the said groove, and thereby replaces the mandrel 14 into its initial position. In its backward movement the mandrel 14 engages with its slit the edge of the sheet under operation, which sheet has been lowered with the table 46, as has been mentioned heretofore. The forward-and backward movement of the mandr'el14 being terminated owing to the intermittent working of the pinions 41 and 42, the disk 39 ceases to turn, while the mandrel 14 now begins its rotation, thereby rolling the sheet engaged in its slit, and the brush 56, fille'd with glue in its part e Z on by the pallet 51, which draws the glue from the receptacle 70, glues the sheet which is pressed against the mandrel by the bar 72. When the rolling of the tube is efiected, the bar 72 is lowered,- while the tube is finished by the action of the dry part m n d of the brush 56, which latter is freed from the glue wherewith it may be still filled by the friction exercised on it's periphery by the bar 71. It remains now to take oif the finished tube from the mandrel. This operation is effected in the following manner: The brush now presents its inactive part at c, Fig. 6. Now in the same time while the table 46 rises and the support 76 moves forward into the position shown by mixed lines in Fig. 6 the mandrel 14 is withdrawn for a new operation. As the finished tube butts with its one end against the face h of the support 25 while the mandrel enters into the hollow shaft 16, the tube glides from the mandrel and is dropped on the support 76, so as to prevent it from falling into the receptacle 70, whereafter the support 76 returns to its initial position. In the meantime the operator places another sheet of paper, cardboard, or pasteboard on the lifted table, and therewith begins a new cycle of operation, to be accomplished under the same conditions as heretofore described.

In order to assure a continuous working of the machine, it is therefore suflicient to place on the table 46 one after another the sheets cut up beforehand to the length desired for the tubes to be manufactured.
